This article details how to use a third party program to swap the clock and action center.
For lazy people:
This is the program you need.
And the instruction from the website:
- Point your browser to the author's GitHub (the link above). There, you'll find the app's source code along with the compiled binaries.
- Download everything by clicking "Clone or Download -> Download ZIP". Then unpack the binaries to any folder.
- If you are running a 32-bit Windows 10 version, go to the folder CPR_x86. Otherwise, go to the folder CPR_x64. Right click the file
ClockPositionRighteousifier.exe and open its properties. Tick
"Unblock" in the properties window. Repeat this step for cprdll.dll.
- Once this is done, you can start ClockPositionRighteousifier.exe. The date/time and Action Center icons will be swapped, with the clock
moving to the end of the taskbar.
